“Do this run to celebrate all that you love about running. . . and to experience the grandeur of a spectacular part of the world.”

Martina Ritchie

Ran the Half. Loved everything. Water stops were fully stocked for the entire Half, unbelievable! Wonderful volunteers. Beautiful course. Don’t know why the race is so small. Am definitely running it next year!

This was my first marathon, and I can’t speak highly enough about my experience at this race. Great volunteers, AMAZING aid stations, and breathtaking scenery. The weather was perfect throughout the entire day. It’s a very small race, so if you are looking for lots of spectators or fellow participants- look elsewhere. I’ve never seen aid stations stocked so well- and I’ve run many half marathons and they have nothing on this race!
